18QHTF21-16.773199-PD

Oscillators Overview

The 18QHTF21-16.773199-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 16.773199 MHz and utilizes LVCMOS output logic levels. The device is designed for low-voltage applications, functioning at 1.8V. It features a power-down capability via a standby control pin to reduce consumption when inactive. The component is housed in a compact 4-SMD, no-lead package with dimensions of 2.0x1.6 mm, suitable for surface-mount assembly on printed circuit boards.

Oscillators Feature Summary

• Supports LVCMOS output signal compatibility
• Includes standby mode for power reduction
• Compact 4-SMD no-lead surface mount package

Oscillators Applications

• Digital communication systems requiring precise clocking
• Consumer electronics with space constraints
• Industrial control modules needing stable timing references

Oscillators Procurement Notes

Verify the specific ordering suffix 'PD' confirms the power-down feature against the manufacturer's official datasheet. Ensure the voltage rating matches the system design requirements. Confirm the package type aligns with PCB footprint specifications before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a 1.8V supply is available and low power consumption during idle states is required. The small form factor makes it ideal for dense layouts. Verify that the LVCMOS output swing is compatible with the receiving logic inputs of the target application circuit.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies and control options. The '-PD' suffix specifically denotes the inclusion of a power-down function, distinguishing it from standard enable/disable or always-on variants within the same family.

Oscillators Replacement Considerations

Direct substitutes must match the 16.773199 MHz frequency, 1.8V operation, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and electrical characteristics with alternative manufacturers before integration.
